Answer:
10x² + 6x + 3xy + 3y - y²
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, as shown
(2x + y)(5x - y + 3)
= 2x(5x - y + 3) + y(5x - y + 3) ← distributing
= 10x² - 2xy + 6x + 5xy - y² + 3y ( collect like terms )
= 10x² + 6x + 3xy + 3y - y²
Because the altitude of parallelogram is perpendicular to the base and it is the height of the parallelogram so in this way every choices B. and C. are right sure
but than you check so choice - but there is something mistake bc. you wrote two choices D. so the second what say ,,it is used in finding area of a parallelogram" is right too
hope helped
Answer: i dont get what u mean explain
Step-by-step explanation:
Answer:
Statement 3: DC=CD (Common)
Step-by-step explanation:
According from the statement given, consider ΔADC and ΔBCD, we get
AD=BC(opposite sides of a rectangle are congruent)
∠ADC=∠BCD(angles of a rectangle are 90°)
DC=CD(Common)
Thus, by SAS rule, ΔADC≅ΔBCD and by CPCTC AC=BD.
Thus, Statement 3 that is using the common sides of the triangle jimmy can prove the proof.
Step-by-step explanation:
3e <= 6
e <= 2 (divide 3 on both sides)
The e-values that satisfy the inequality are:
e = 1 and e = 2.
